    Unlocking the Secrets of Skilled Professions

    Sample interview questions: How do you ensure that plumbing systems are designed for effective rainwater collection and disposal?

    Sample answer:

    1. Analyze Rainfall Patterns:
    2. Study historical rainfall data to understand the average rainfall, peak rainfall intensity, and duration for the area.
    3. Categorize the rainfall patterns into light, moderate, and heavy rainfall events to design systems accordingly.

    4. Determine Runoff Coefficients:

    5. Assess the impervious surfaces (roofs, driveways, patios) and pervious surfaces (lawns, gardens) to determine the runoff coefficients.
    6. Runoff coefficients represent the proportion of rainfall that becomes runoff.

    7. Calculate Peak Runoff:

    8. Utilize the Rational Method or applicable stormwater management models to calculate the peak runoff rate for each rainfall event.
    9. Consider factors like drainage area, rainfall intensity, and time of concentration in the calculations.

    10. Design Rainwater Collection Systems:

    11. Size rainwater storage tanks or cisterns based on the anticipated runoff volume and desired storage capacity.
    12. Ensure the collection system has adequate inlets, gutters, and downspouts to capture rainwater efficiently.
    13. Include filtration and pretreatment systems to remove debris and contaminants from rainwater.

    14. Design Rainwater Disposal Systems:

    15. Evaluate available disposal options, including infiltration, reuse, or discharge to a stormwater system.
    16. Design infiltration systems, such as dry wells or infiltration trenches, to allow rainwater to percolate… Read full answer
